4. Operation
4.1. Basic Principles
On completion of installation of the Profiler(s) on a vehicle, they can be tested
in air by powering up the system and observing that the red LED illuminates
as the head scans through the ahead direction.
The Profiler heads can be run in Single or Dual head modes. The head has
a minimum lockout range of 0.3 metres and will not display returns below
this range. The lockout value can be adjusted from the
Setup
option in the
Application Tools
menu (right-click on the sonar screen).
Each head will have a separate node number in Seanet Pro (typically 20
for "Master" and 21 for "Slave") - the head that is programmed with the
lowest node number of the pair is the Master or controlling head. If a head is
enabled and is not physically connected, an error status message will flash
on-screen to inform the operator that a profiler head has not been detected
so unconnected heads should be disabled to prevent interruptions.
A synchronisation link is setup between a dual head pair on pin 5 line. When
pin 5 is linked, the Master head is responsible for taking control of the pair
and establishing Scan and Ping syncs if these have been configured during
head setup.
There are 4 range resolutions available; Low, Medium, High and Ultra,
selected from the Profiler Settings bar. As the resolution is increased from
Low to Medium to High to Ultra, the Profiler display will plot more points within
the scan, therefore use of a lower resolution will give faster scan speeds, but
at a lower level of detail.
